BUT!!!
They got a GPWS warning, responded appropriately, and lived to tell the tale.
A long night , back of the clock, no radar and now program the FMC, I couldn't say that that was an un-makeable mistake.
Accepted that with known terrain etc situational awareness is critical, but how many servicable aircraft fly into hills with "woop woop" screaming into the drivers ears?
There but for the grace of god......
